        PROXY STATEMENT

             The enclosed Proxy is solicited by the Board of Directors of
        Thermo Process Systems Inc. (the "Corporation") for use at the
        1995 Annual Meeting of the Stockholders (the "Meeting") to be
        held on Wednesday, December 13, 1995, at 5:00 p.m. at the
        Sheraton Tara Lexington Inn, 73 Marrett Road, Lexington,
        Massachusetts, and any adjournment thereof. The mailing address
        of the executive office of the Corporation is 81 Wyman Street,
        Waltham, Massachusetts 02254.  This Proxy Statement and the
        enclosed Proxy were first furnished to Stockholders of the
        Corporation on or about November 9, 1995.

        VOTING PROCEDURES

             The Board of Directors intends to present to the Meeting the
        election of six Directors, constituting the entire Board of
        Directors, as well as two other matters: a proposal to amend the
        Corporation's Certificate of Incorporation to change the
        Corporation's name to "Thermo TerraTech Inc." and a proposal to
        amend the Directors Stock Option Plan to change the formula for
        the award of stock options to purchase common stock of the
        Corporation to its outside Directors and also to provide for the
        automatic grant to its outside Directors of stock options to
        purchase common stock of the Corporation's majority-owned
        subsidiaries created from time to time.
         
             The representation in person or by proxy of a majority of
        the outstanding shares of common stock of the Corporation, $.10
        par value ("Common Stock"), entitled to vote at the Meeting is
        necessary to provide a quorum for the transaction of business at
        the Meeting. Shares can only be voted if the Stockholder is
        present in person or is represented by returning a properly
        signed proxy. Each Stockholder's vote is very important. Whether
        or not you plan to attend the Meeting in person, please sign and
        promptly return the enclosed proxy card, which requires no
        postage if mailed in the United States.  All signed and returned
        proxies will be counted towards establishing a quorum for the
        Meeting, regardless of how the shares are voted.
         
             Shares represented by proxy will be voted in accordance with
        your instructions. You may specify your choice by marking the
        appropriate box on the proxy card. If your proxy card is signed
        and returned without specifying choices, your shares will be
        voted for the management nominees for Directors, for the
        management proposal, and as the individuals named as proxy
        holders on the proxy deem advisable on all other matters as may
        properly come before the Meeting.

             In order to be elected a Director, a nominee must receive
        the affirmative vote of a majority of the shares of Common Stock
        present and entitled to vote on the election.  For all other
        matters to be voted upon at the Meeting the affirmative vote of a
        majority of shares present in person or represented by proxy, and

                                        2
PAGE





        entitled to vote on the matter, is necessary for approval.
        Withholding authority to vote for a nominee for Director or an
        instruction to abstain from voting on a proposal will be treated
        as shares present and entitled to vote and, for purposes of
        determining the outcome of the vote, will have the same effect as
        a vote against the nominee or a proposal.  A broker "non-vote"
        occurs when a nominee holding shares for a beneficial holder does
        not have discretionary voting power and does not receive voting
        instructions from the beneficial owner.   Broker "non-votes" will
        not be treated as shares present and entitled to vote on a voting
        matter and will have no effect on the outcome of the vote.   
         
             A Stockholder who returns a proxy may revoke it at any time
        before the Stockholder's shares are voted at the Meeting by
        written notice to the Secretary of the Corporation received prior
        to the Meeting, by executing and returning a later-dated proxy or
        by voting by ballot at the Meeting.

             The outstanding stock of the Corporation entitled to vote
        (excluding shares held in treasury by the Corporation) as of
        October 26, 1995, consisted of 17,391,348 shares of Common Stock.
        Only Stockholders of record at the close of business on October
        26, 1995, are entitled to vote at the Meeting. Each share is
        entitled to one vote.

        change in control or proposed change in control of the
        Corporation that is not approved by the Board of Directors,

        following is deemed to be a change of control:  (a) the
        occurrence, without the prior approval of the Board of Directors,
        of the acquisition, directly or indirectly, by any person of 50%
        or more of the outstanding Common Stock or the outstanding common
        stock of Thermo Electron; or (b) the failure of the persons
        serving on the Board of Directors immediately prior to any
        contested election of Directors or any exchange offer or tender
        offer for the Common Stock or the common stock of Thermo Electron
        to constitute a majority of the Board of Directors at any time
        within two years following any such event.  Amounts deferred
        pursuant to the Deferred Compensation Plan are valued on the date
        of deferral as units of the Corporation's Common Stock. When
        payable, amounts deferred may be disbursed solely in shares of
        Common Stock accumulated under the Deferred Compensation Plan. A
        total of 54,000 shares of Common Stock have been reserved for
        issuance under the Deferred Compensation Plan.  As of July 1,
        1995, deferred units equal to 31,838 full shares of Common Stock
        were accumulated under the Deferred Compensation Plan.

             The Corporation's directors stock option plan (the
        "Directors Plan") provides for the grant of stock options to
        purchase shares of Common Stock to outside Directors as
        additional compensation for their service as Directors.  In
        February 1995, the Board of Directors approved amendments to the
        Directors Plan that are subject to Stockholder approval at this
        Meeting.  The amendments are described under Proposal 3 to this
        Proxy Statement.  Prior to the amendment of the Directors Plan,
        eligible Directors were automatically granted 1,000 shares
        annually upon the close of business on the date of the
        Corporation's Annual Meeting of Stockholders and were also
        granted options to purchase Common Stock on a quarterly basis
        according to the following formula:  200 shares for each meeting
        of the Board of Directors held during the quarter and attended in
        person by the recipient and 100 shares for each telephone meeting
        or committee meeting of the Board of Directors held during the
        quarter in which the recipient participated.  The amendments to
        the plan would retain the annual award of 1,000 options (although
        the terms of the award would be modified), but would eliminate
        the quarterly award of stock options based on meeting attendance.
        In addition, the Directors Plan would also provide for the
        automatic grant every five years of options to purchase 1,500
        shares of the common stock of any majority-owned subsidiary of
        the Corporation that is "spunout" to outside investors, including
        a grant of an option to purchase 1,500 shares of Thermo
        Remediation upon the close of business on the date of this
        Meeting.

             The exercise price for options that have been granted to
        date under the Directors Plan is determined by the average of the
        closing prices of the Common Stock as reported on the American
        Stock Exchange for the five trading days preceding and including
        the date of grant. Outstanding options are exercisable six months
        after the date of grant and, if granted prior to 1995, generally
        expire seven years from the date of grant.  An aggregate of
        75,000 shares of Common Stock has been reserved for issuance
        under the Directors Plan. As of July 1, 1995, options to purchase
        16,700 shares of Common Stock were outstanding under the
        Directors Plan at an average exercise price of $8.44 per share,
        no shares of Common Stock had been issued pursuant to the
        exercise of options and no options to purchase shares of Common
        Stock had lapsed.  Options to purchase 58,300 shares of Common
        Stock were reserved and available for grant under the Directors
        Plan as of July 1, 1995.

        Disclosure of Certain Late Filings

             Section 16(a) of the Securities Exchange Act of 1934
        requires the Corporation's Directors and executive officers, and
        beneficial owners of more than 10% of the Common Stock, such as
        Thermo Electron, to file with the Securities and Exchange
        Commission initial reports of ownership and periodic reports of
        changes in ownership of the Corporation's securities.  Based upon
        a review of such filings, all Section 16(a) filing requirements
        applicable to such persons were complied with during fiscal 1995,
        except in the following instances.  The initial report of
        ownership for one of the Corporation's executive officers, Mr.
        Bruce J. Taunt, failed to include 20.2 shares of Common Stock
        allocated to his account under the Thermo Electron ESOP, and
        failed to include 160 shares of Common Stock beneficially held by
        trust.  These deficiencies were corrected in an amendment to his
        Form 3 on January 25, 1995, except for the trust holdings which
        were reported on his Form 5 filed in May 1995.  In addition, the
        fiscal 1994 Form 5 filed on behalf of Mr. John N. Hatsopoulos, a
        Director and the Chief Financial Officer of the Corporation,
        failed to report three gifts of shares of Common Stock
        aggregating 4,000 shares.  The gifts were reported in an
        amendment to Mr. Hatsopoulos' Form 5 filed on October 12, 1994.
        Thermo Electron reported purchases of the Corporation's 6-1/2%
        Convertible Subordinated Debentures late on two occasions.  It
        reported the purchase in March 1994 of $1,150,000 principal
        amount of such debentures in May 1994 on its Form 5 and another
        purchase in March 1995 of $365,000 principal amount of such
        debentures in an amendment filed seven days late.  In addition,
        in converting Form 4 records of the Corporation from a manual
        system to a computer database, it was discovered that Thermo
        Electron failed to report the sale in August 1992 of $250,000
        principal amount of the Corporation's 6-1/2% Convertible
        Subordinated Debentures.  The sale was reported on the Form 5
        filed by Thermo Electron in May 1995.

        EXECUTIVE COMPENSATION

             The following table summarizes compensation for services to
        the Corporation in all capacities awarded to, earned by or paid
        to the Corporation's chief executive officer and its two other
        most highly compensated executive officers for the last three
        fiscal years.  No other executive officers of the Corporation who
        held office during fiscal 1995 met the definition of "highly
        compensated" within the meaning of the Securities and Exchange
        Commission's executive compensation disclosure rules for such
        period.  

             The Corporation is required to appoint certain executive
        officers and full-time employees of Thermo Electron as executive
        officers of the Corporation, in accordance with the Thermo
        Electron Corporate Charter. The compensation for these executive
        officers is determined and paid entirely by Thermo Electron. The
        time and effort devoted by these individuals to the Corporation's

                                       12

        affairs is provided to the Corporation under the Corporate
        Services Agreement between the Corporation and Thermo Electron.
        Accordingly, the compensation for these individuals is not

        respectively.  Dr. Appleton has served as an officer of Thermo

        shares of the common stock of Thermo Electron and certain of its
        subsidiaries other than the Corporation from time to time by
        Thermo Electron or such other subsidiaries.  These options are
        not reported in this table as they were granted as compensation
        for service to other Thermo Electron companies in capacities
        other than in his capacity as the president and chief executive
        officer of the Corporation.

        (2)  Represents the amount of matching contributions made on
        behalf of the executive officers participating in Thermo
        Electron's 401(k) plan.

        (3)  Dr. Appleton was appointed president and chief executive
        officer of the Corporation effective September 1, 1993.  Dr.
        Appleton is also a vice president of Thermo Electron.  Reported
        in the table under "Annual Compensation" are the total amounts
        paid to Dr. Appleton for his service in all capacities to Thermo
        Electron companies since September 1, 1993.  The Human Resources
        Committee of the Board of Directors of the Corporation reviews
        total annual cash compensation to be paid to Dr. Appleton from
        all sources within the Thermo Electron organization and approves
        the allocation of a percentage of annual cash compensation
        (salary and bonus) for the time he devotes to the affairs of the
        Corporation.  For fiscal 1995 and 1994, 85% and 100%,
        respectively, of Dr. Appleton's reported cash compensation was
        allocated to the Corporation.  These percentages include the
        allocation of a portion of Dr. Appleton's annual cash
        compensation attributable to the management of the Thermo Terra
        Tech joint venture, which was acquired by the Corporation in
        April 1995 in a transaction accounted for in a manner similar to
        pooling of interests accounting. Bonuses paid to Dr. Appleton
        reflect compensation decisions based on calendar year
        performance, in accordance with Thermo Electron's compensation
        practices for its officers.

        (4)  In fiscal 1994, the Corporation changed its compensation
        practices for executive officers (other than the chief executive
        officer who continues to be reviewed on a calendar year
        performance) to make compensation decisions based on fiscal year
        performance rather than calendar year performance.  As a
        consequence, the bonus paid to Mr. Powell in fiscal 1994 related
        to a 15-month period from January 3, 1993 through April 2, 1994.

        (5)  Mr. Taunt was appointed an executive officer of the
        Corporation on November 1, 1994.

             The following table sets forth information concerning
        individual grants of stock options made during fiscal 1995 to the
        Corporation's chief executive officer and the other named
        executive officers. It has not been the Corporation's policy in
        the past to grant stock appreciation rights, and no such rights
        were granted during fiscal 1995.  

             Dr. Appleton has served as a vice president of Thermo
        Electron since 1975 and from time to time has been granted
        options to purchase common stock of Thermo Electron and certain
        of its subsidiaries other than the Corporation and Thermo
        Remediation.  These options are not reported in this table as
        they were granted as compensation for service to other Thermo
        Electron companies in capacities other than in his capacity as
        the chief executive officer of the Corporation.

        (1)  In addition to the grant of options to purchase Common Stock
        of the Corporation (designated in the table as TPI), options have
        been granted during fiscal 1995 to the named executive officers
        to purchase the common stock of Thermo Electron (designated in
        the table as TMO) and Thermo Remediation (designated in the table
        as THN).  All of the options granted during the fiscal year are
        immediately exercisable at the date of grant. However, the shares
        acquired upon exercise are subject to repurchase by the granting
        corporation at the exercise price if the optionee ceases to be
        employed by the granting corporation or another Thermo Electron
        company. The granting corporation may exercise its repurchase
        rights within six months after the termination of the optionee's
        employment. The repurchase rights lapse ratably over a five- to
        ten-year period, depending on the option term, which may vary
        from seven to twelve years, provided that the optionee continues
        to be employed by the Corporation or another Thermo Electron

                                       17

        company.  The granting corporation may permit the holders of such
        options to exercise options and to satisfy tax withholding
        obligations by surrendering shares equal in fair market value to
        the exercise price or withholding obligation.  The shares of
        common stock of Thermo Electron and Thermo Remediation shown in
        the table reflect a three-for-two split of each such stock
        effected on May 24, 1995 and March 31, 1995, respectively.

        (2)  These options were granted under stock option plans
        maintained by Thermo Electron and accordingly are reported as a
        percentage of total options granted to employees of Thermo
        Electron and its subsidiaries.

        (3)  Options to purchase 15,000 shares of the common stock of
        Thermo Electron granted to Mr. Powell are subject to the same
        terms as described in footnote (1), except that the repurchase
        rights of the granting corporation generally do not lapse until
        the tenth anniversary of the grant date.  In the event of the
        employee's death or involuntary termination prior to the tenth
        anniversary of the grant date, the repurchase rights of the
        granting corporation shall be deemed to have lapsed ratably over
        a five-year period commencing with the fifth anniversary of the
        grant date.

        (1)  All of the options reported outstanding at the end of the
        fiscal year were immediately exercisable at the date of grant.
        However, the shares acquired upon exercise of the options
        reported in the table are subject to repurchase by the granting
        corporation at the exercise price if the optionee ceases to be
        employed by such corporation or any other Thermo Electron
        company. The granting corporation may exercise its repurchase
        rights within six months after the termination of the optionee's
        employment. The repurchase rights generally lapse ratably over a
        five- to ten-year period, depending on the option term, which may
        vary from seven to twelve years, provided that the optionee
        continues to be employed by the Corporation or another Thermo
        Electron company.  

        (2)  Dr. Appleton has served as a vice president of Thermo
        Electron since 1975 and holds unexercised options to purchase
        common stock of Thermo Electron and certain of its subsidiaries
        other than the Corporation and Thermo Remediation. These options
        are not reported here as they were granted as compensation for
        service to other Thermo Electron companies in capacities other
        than in his capacity as the chief executive officer of the
        Corporation.

        (3)  In addition to the terms described in footnote (1) above,
        shares acquired upon exercise of these options are restricted
        from resale until Dr. Appleton's retirement.

        (4)  Of these options awarded to Mr. Powell and Mr. Taunt,
        options to purchase 15,000 shares each are subject to the
        following terms in addition to those described in footnote (1):
        In the event of the optionee's voluntary resignation or discharge
        for cause prior to February 8, 1998, all of the shares acquired
        upon exercise of these options are subject to repurchase by the
        Corporation at the exercise price.  In addition, all shares

                                       19
PAGE





        acquired upon the exercise of these options are subject to
        restrictions on resale until February 8, 1998.

        (5)  Options to purchase 15,000 shares of the common stock of
        Thermo Electron granted to Mr. Powell are subject to the same
        terms as described in footnote (1), except that the repurchase
        rights of the granting corporation generally do not lapse until
        the tenth anniversary of the grant date.  In the event of the
        employee's death or involuntary termination prior to the tenth
        anniversary of the grant date, the repurchase rights of the
        granting corporation shall be deemed to have lapsed ratably over
        a five-year period commencing with the fifth anniversary of the
        grant date.

        SEVERANCE and Other AGREEMENTS

             Thermo Electron has entered into severance agreements with
        several key employees, including Dr. Appleton.  These agreements
        provide severance benefits if there is a change of control of
        Thermo Electron that is not approved by the Board of Directors of
        Thermo Electron and the employee's employment with Thermo
        Electron or one of its majority-owned subsidiaries is terminated,
        for whatever reason, within one year thereafter.  For purposes of
        the agreements, a change of control exists upon (i) the
        acquisition of 50% or more of the outstanding common stock of
        Thermo Electron by any person without the prior approval of the
        board of directors of Thermo Electron, (ii) the failure of the
        board of directors of Thermo Electron, within two years after any
        contested election of directors or tender or exchange offer not
        approved by the board of directors, to be constituted of a
        majority of directors holding office prior to such event or (iii)
        any other event that the board of directors of Thermo Electron
        determines constitutes an effective change of control of Thermo
        Electron.  The benefit under these agreements is stated as an
        initial percentage which was established by the Board of
        Directors of Thermo Electron and was generally based upon the
        employee's age and length of service with Thermo Electron at the
        time of severance.  Benefits are to be paid over a five-year
        period.  The benefit to be paid in the first year is determined
        by applying this percentage to the employee's highest annual
        total remuneration in any 12-month period during the preceding
        three years.  This benefit is reduced by 10% in each of the
        succeeding four years in which benefits are paid.  The initial
        percentage to be so applied to Dr. Appleton is 40.1%.  Assuming
        severance benefits would have been payable under such agreements
        as of July 1, 1995, Dr. Appleton would have received
        approximately $100,000 in the first year thereof from Thermo
        Electron. 


        COMMITTEE REPORT ON EXECUTIVE COMPENSATION

        EXECUTIVE COMPENSATION



                                       20
PAGE





             All decisions on compensation for the Corporation's
        executive officers are made by the Human Resources Committee of
        the Board of Directors (the "Committee").  In reviewing and
        establishing total cash compensation and stock-based compensation
        for executives, the Committee follows guidelines established by
        the human resources committee of the board of directors of its
        parent corporation, Thermo Electron. The executive compensation
        program presently consists of annual base salary ("salary"),
        short-term incentives in the form of annual cash bonuses, and
        long-term incentives in the form of stock options. 

             The Committee believes that the compensation of executive
        officers should reflect the scope of their responsibilities, the
        success of the Corporation, and the contributions of each
        executive to that success.  In addition, the Committee believes
        that base salaries should approximate the mid-point of
        competitive salaries derived from market surveys and that
        short-term and long-term incentive compensation should reflect
        the performance of the Corporation and the contributions of each
        executive.

             External competitiveness is an important element of the
        Committee's compensation policy.  The competitiveness of the
        Corporation's compensation for its executives is assessed by
        comparing it to market data provided by its compensation
        consultant and by participating in annual executive compensation
        surveys, primarily "Project 777", an executive compensation
        survey prepared by Management Compensation Services, a division
        of Hewitt Associates.  The majority of firms represented in the
        Project 777 survey are included in the Standard & Poor's Index,
        but do not necessarily correspond to the companies included in
        the Corporation's peer group index.

             Principles of internal equity are also central to the
        Committee's compensation policies.  Compensation considered for
        the Corporation's officers, whether cash or stock-based
        incentives, is also evaluated by comparing it to compensation of
        other executives within the Thermo Electron organization with
        comparable levels of responsibility for comparably sized business
        units.

             The process for determining each of these elements for the
        Corporation's executive officers is outlined below.

             Base Salary

             Base salaries are intended to approximate the mid-point of
        competitive salaries for similar organizations of comparable size
        and complexity to the Corporation.  Executive salaries are
        adjusted gradually over time and only as necessary to meet this
        objective.  Increases in base salary may be moderated by other
        considerations, such as geographic or regional market data,
        industry trends or internal fairness within the Corporation and
        Thermo Electron.  It is the Committee's intention that over time
        the base salaries for the chief executive officer and its other

                                       21
PAGE





        named executive officers will approach the mid-point of
        competitive data.  The salary increases in fiscal 1995 for the
        chief executive officer and the other named executive officers
        generally reflect this practice of gradual increases and
        moderation.

             CASH BONUS
         
             The Committee establishes a median potential bonus for each
        executive by using the market data on total cash compensation
        from the same executive compensation surveys as used to determine
        salaries.  Specifically, the median potential bonus plus the
        salary of an executive officer is approximately equal to the
        mid-point of competitive total cash compensation for a similar
        position and level of responsibility in businesses having
        comparable sales and complexity to the Corporation. The actual
        bonus awarded to an executive officer may range from minus one to
        three times the median potential bonus. The value within the
        range (the bonus multiplier) is determined at the end of each
        year by the Committee in its discretion.  The Committee exercises
        its discretion by evaluating each executive's performance using a
        methodology developed by its parent corporation, Thermo Electron,
        and applied throughout the Thermo Electron organization.  The
        methodology incorporates measures of operating returns, designed
        to measure profitability, contributions to shareholder value, and
        earnings growth, and are measures of corporate and divisional
        performance that are evaluated using graphs developed by Thermo
        Electron designed to reward performance that is perceived as
        above average and to penalize performance that is perceived as
        below average.  The measures of operating returns used in the
        Committee's determinations in fiscal 1995 measured return on net
        assets, growth in income, and growth in earnings per share and
        the Committee's determinations also included an evaluation of the
        contributions of each executive that are not captured by
        operating measures but are considered important to the creation
        of long-term value for the stockholders.   These measures of
        achievements are not financial targets that are met, not met or
        exceeded. The relative importance of these factors varies
        depending on the executive's role and responsibilities within the
        organization.

             The bonuses for named executive officers approved by the
        Committee with respect to fiscal 1995 performance in each
        instance exceeded the median potential bonus.

        STOCK OPTION PROGRAM

             The primary goal of the Corporation is to excel in the
        creation of long-term value for the Stockholders. The principal
        incentive tool used to achieve this goal is the periodic award to
        key employees of options to purchase common stock of the
        Corporation and other Thermo Electron companies.

             The Committee and management believe that awards of stock
        options to purchase the shares of both the Corporation and other

                                       22

        companies within the Thermo Electron group of companies
        accomplish many objectives. The grant of options to key employees
        encourages equity ownership in the Corporation, and closely
        aligns management's interests to the interests of all the
        Stockholders. The emphasis on stock options also results in
        management's compensation being closely linked to stock
        performance. In addition, because they are subject to vesting
        periods of varying durations and to forfeiture if the employee
        leaves the Corporation prematurely, stock options are an
        incentive for key employees to remain with the Corporation
        long-term. The Committee believes stock option awards in its
        subsidiary, Thermo Remediation and its parent corporation, Thermo
        Electron, and the other majority-owned subsidiaries of Thermo
        Electron, are an important tool in providing incentives for
        performance within the entire organization.

             In determining awards, the Committee considers the average
        annual value of all options to purchase shares of the Corporation
        and other companies within the Thermo Electron organization that
        vest in the next five years.  (Values are established using a
        modified Black-Scholes option pricing model.)  As a guideline,
        the Committee strives to maintain the aggregate amount of awards
        to all employees over a five-year period below 10% of the
        Corporation's outstanding common stock, although other factors
        such as unusual transactions and acquisitions and standards for
        awards of comparably situated companies may affect the number of
        awards granted.

             Awards are not made annually in conjunction with the annual
        review of cash compensation, but are made periodically.  The
        Committee considers total compensation of executives, actual and
        anticipated contributions of each executive (which includes a
        subjective assessment by the Committee of the value of the
        executive's future potential within the organization), as well as
        the value of previously awarded options as described above, in
        determining option awards.  The option awards made with respect
        to the common stock of the Corporation's parent, Thermo Electron,
        and its subsidiary, Thermo Remediation, were determined by the
        human resources committee of the board of directors of each such
        company using a similar analysis.

        Policy on Deductibility of Compensation

             The Committee has also considered the application of Section
        162(m) of the Internal Revenue Code to the Corporation's
        compensation practices.  Section 162(m) limits the tax deduction
        available to public companies for annual compensation paid to
        senior executive in excess of $1 million, unless the compensation
        qualifies as "performance based".  The annual cash compensation
        paid to individual executives does not approach the $1 million
        threshold, and it is believed that the stock incentive plans of
        the Corporation qualify as "performance based".  Therefore, the
        Committee does not believe any further action is necessary in
        order to comply with Section 162(m).  From time to time, the


                                       23
PAGE





        Committee will reexamine the Corporation's compensation practices
        and the effect of Section 162(m).

        CEO COMPENSATION
         
             Cash compensation for Dr. Appleton is reviewed by both the
        Committee and the human resources committee of the board of
        directors of Thermo Electron (the "Thermo Electron Committee"),
        due to his responsibilities as both the Corporation's chief
        executive officer and as a vice president of Thermo Electron.
        Each committee evaluates Dr. Appleton's performance and proposed
        compensation using a process similar to that used for the other
        executive officers of the Corporation.  At the Thermo Electron
        level, Dr. Appleton is evaluated on his performance related to
        the Corporation as well as other operating units of Thermo
        Electron for which he is responsible, weighted in accordance with
        the amount of time and effort devoted to each operation.   The
        Corporation's Committee then reviews the analysis and
        determinations of the Thermo Electron committee, makes an
        independent assessment of Dr. Appleton's performance as it
        relates to the Corporation using criteria similar to that used
        for the other executive officers of the Corporation, and then
        agrees to an appropriate allocation of Dr. Appleton's
        compensation to be paid by the Corporation.

             In December 1994, the Committee conducted its review of Dr.
        Appleton's  proposed salary for calendar 1995 and bonus for
        calendar 1995 performance.  The Committee concurred in the
        recommendations made by the Thermo Electron Committee and agreed
        to an allocation of 70% of Dr. Appleton's total cash compensation
        for calendar year 1994 and 1995 to the Corporation, based on his
        relative responsibilities at the Corporation (including
        management of the former Thermo Terra Tech joint venture - see
        "Relationship With Affiliates") and Thermo Electron.  Because Dr.
        Appleton's bonus for calendar 1994 performance is paid in
        calendar 1995, 70% of such bonus has been allocated to the
        Corporation.  The Committee believes that the total cash
        compensation for Dr. Appleton for calendar 1994 tends to be below
        the competitive norm for a similarly sized company with
        performance comparable to that of the Corporation, and prefers
        that a significant portion of total compensation be awarded in
        the form of long-term incentive compensation, such as stock
        options.

        RELATIONSHIP WITH AFFILIATES

             Thermo Electron has adopted a strategy of selling a minority
        interest in subsidiary companies to outside investors as an
        important tool in its future development. As part of this
        strategy, the Corporation has created Thermo Remediation as a
        majority-owned publicly held subsidiary.  From time to time,
        Thermo Electron and its subsidiaries will create other
        majority-owned subsidiaries as part of its spinout strategy.
        (The Corporation and the other Thermo Electron subsidiaries are
        hereinafter referred to as the "Thermo Subsidiaries".)
         
             Thermo Electron and each of the Thermo Subsidiaries
        recognize that the benefits and support that derive from their
        affiliation are essential elements of their individual
        performance. Accordingly, Thermo Electron and each of the Thermo
        Subsidiaries have adopted the Thermo Electron Corporate Charter
        (the "Charter") to define the relationships and delineate the
        nature of such cooperation among themselves. The purpose of the
        Charter is to ensure that (1) all of the companies and their
        stockholders are treated consistently and fairly, (2) the scope
        and nature of the cooperation among the companies, and each
        company's responsibilities, are adequately defined, (3) each
        company has access to the combined resources and financial,
        managerial and technological strengths of the others, and (4)
        Thermo Electron and the Thermo Subsidiaries, in the aggregate,
        are able to obtain the most favorable terms from outside parties.
         
             To achieve these ends, the Charter identifies the general
        principles to be followed by the companies, addresses the role
        and responsibilities of the management of each company, provides
        for the sharing of group resources by the companies and provides
        for centralized administrative, banking and credit services to be
        performed by Thermo Electron. The services provided by Thermo
        Electron include collecting and managing cash generated by
        members, coordinating the access of Thermo Electron and the
        Thermo Subsidiaries (the "Thermo Group") to external financing
        sources, ensuring compliance with external financial covenants
        and internal financial policies, assisting in the formulation of
        long-range financial planning and providing other banking and
        credit services. Pursuant to the Charter, Thermo Electron may
        also provide guarantees of debt or other obligations of the
        Thermo Subsidiaries or may obtain external financing at the
        parent level for the benefit of the Thermo Subsidiaries. In
        certain instances, the Thermo Subsidiaries may provide credit
        support to, or on behalf of, the consolidated entity or may
        obtain financing directly from external financing sources. Under
        the Charter, Thermo Electron is responsible for determining that
        the Thermo Group remains in compliance with all covenants imposed
        by external financing sources, including covenants related to
        borrowings of Thermo Electron or other members of the Thermo
        Group, and for apportioning such constraints within the Thermo
        Group.  In addition, Thermo Electron is also responsible for
        establishing internal policies and procedures. The cost of the
        services provided by Thermo Electron to the Thermo Subsidiaries

                                       28
PAGE





        is covered under existing corporate services agreements between
        Thermo Electron and each of the Thermo Subsidiaries.

             The Charter presently provides that it shall continue in
        effect so long as Thermo Electron and at least one Thermo
        Subsidiary participate. The Charter may be amended at any time by
        agreement of the participants. Any Thermo Subsidiary, including
        the Corporation, can withdraw from participation in the Charter
        upon 30 days' prior notice. A subsidiary's participation in the
        Charter will terminate in the event the subsidiary ceases to be
        controlled by Thermo Electron or ceases to comply with the
        Charter or the policies and procedures applicable to the Thermo
        Group. A withdrawal from the Charter automatically terminates the
        corporate services agreement and tax allocation agreement (if
        any) in effect between the withdrawing company and Thermo
        Electron. The withdrawal from participation does not terminate
        outstanding commitments to third parties made by the withdrawing
        company, or by Thermo Electron or other members of the Thermo
        Group, prior to the withdrawal. However, a withdrawing company is
        required to continue to comply with all policies and procedures
        applicable to the Thermo Group and to provide certain
        administrative functions mandated by Thermo Electron so long as
        the withdrawing company is controlled by or affiliated with
        Thermo Electron.

             As provided in the Charter, the Corporation and Thermo
        Electron have entered into a Corporate Services Agreement (the
        "Services Agreement") under which Thermo Electron's corporate
        staff provides certain administrative services, including certain
        legal advice and services, risk management, certain employee
        benefit administration, tax advice and preparation of tax
        returns, centralized cash management and certain financial and
        other services to the Corporation.  Prior to January 1, 1995,  
        the Corporation was assessed an annual fee equal to 1.25% of the
        Corporation's revenues for these services. Effective January 1,
        1995, the fee has been reduced to 1.2% of the Corporation's
        revenues. The fee is reviewed annually and may be changed by
        mutual agreement of the Corporation and Thermo Electron.  During
        fiscal 1995, Thermo Electron assessed the Corporation $1,653,000
        in fees under the Services Agreement.  Management believes that
        the charges under the Services Agreement are reasonable and that
        the terms of the Services Agreement are representative of the
        expenses the Corporation would have incurred on a stand-alone
        basis. For items such as employee benefit plans, insurance
        coverage and other identifiable costs, Thermo Electron charges
        the Corporation based on charges attributable to the Corporation.
        The Services Agreement automatically renews for successive
        one-year terms, unless canceled by the Corporation upon 30 days'
        prior notice.  In addition, the Services Agreement terminates
        automatically in the event the Corporation ceases to be a member
        of the Thermo Group or ceases to be a participant in the Charter.
        In the event of a termination of the Services Agreement, the
        Corporation will be required to pay a termination fee equal to
        the fee that was paid by the Corporation for services under the
        Services Agreement for the nine-month period prior to

                                       29
PAGE





        termination. Following termination, Thermo Electron may provide
        certain administrative services on an as-requested basis by the
        Corporation or as required in order to meet the Corporation's
        obligations under Thermo Electron's policies and procedures.
        Thermo Electron will charge the Corporation a fee equal to the
        market rate for comparable services if such services are provided
        to the Corporation following termination.

               From time to time, the Corporation may transact business
        in the ordinary course with other companies in the Thermo Group.
        All such transactions are on terms comparable to those the
        Corporation would receive from unaffiliated parties.

             As of April 1, 1995, $30,802,000 of the Corporation's cash
        equivalents were invested in a repurchase agreement with Thermo
        Electron. Under this agreement, the Corporation in effect lends
        excess cash to Thermo Electron, which Thermo Electron
        collateralizes with investments principally consisting of
        corporate notes, U.S. government agency securities, money market
        funds, commercial paper and other marketable securities, in the
        amount of at least 103% of such obligation. The Corporation's
        funds subject to the repurchase agreement are readily convertible
        into cash by the Corporation and have a maturity of three months
        or less. The repurchase agreement earns a rate based on the
        Commercial Paper Composite Rate plus 25 basis points, set at the
        beginning of each quarter.

             The Corporation leases or subleases two office and
        manufacturing facilities from Thermo Electron.  The total rental
        payments made to Thermo Electron during fiscal year 1995 under
        these agreements was $537,000.   

             The Corporation and Thermo Electron entered into a
        development agreement under which Thermo Electron agreed to fund
        up to $4,000,000 of the direct and indirect costs of the
        Corporation's development of soil-remediation centers.  In
        exchange for this funding, the Corporation granted Thermo
        Electron a royalty equal to approximately 3% of net revenues from
        soil-remediation services performed at the centers developed
        under this agreement.  The royalty payments may cease if the
        amounts paid by the Corporation yield a certain internal rate of
        return to Thermo Electron on the funds advanced to the
        Corporation under this agreement.  The Corporation paid Thermo
        Electron royalties of $432,000 in fiscal 1995.

             In February 1995, the Corporation acquired all of the
        outstanding capital stock of Engineering, Technology and
        Knowledge Corporation and its subsidiary, Elson T. Killam
        Associate Inc. ("Killam") from Nord Est S.A., a French industrial
        company, for $12,566,000 in cash and a zero coupon promissory
        note with a then-present value of $22,300,000.  In a related
        transaction, certain members of Killam's senior management
        exchanged options to purchase Killam's common stock for options
        to purchase the Corporation's Common Stock and canceled other
        options in exchange for cash payments in the aggregate amount of

                                       30
PAGE





        $1,922,000.  The Corporation borrowed the cash portion of the
        purchase price, including cash used to collateralize the
        promissory note delivered to Nord Est S.A., from Thermo Electron
        through the issuance of a $38,000,000 promissory note that bears
        interest at the Commercial Paper Composite Rate as announced from
        time to time by Merrill Lynch Capital Markets plus 25 basis
        points and is due June 1, 1997.  As of April 1, 1995, the
        Corporation owed Thermo Electron an aggregate of $56,116,000. 

             Effective April 2, 1995, the Corporation agreed to dissolve
        the Thermo Terra Tech joint venture with Thermo Instrument
        Systems Inc. ("THI"), another subsidiary of Thermo Electron, and
        to purchase the businesses originally contributed to the joint
        venture by THI and formerly operated by the joint venture from
        THI for $34,267,000 in cash.  The purchase price was based on the
        Corporation's determination (as approved by its Board of
        Directors) of the fair market value of the businesses, and the
        terms of the agreement for the purchase were determined by arms'
        length negotiation among the parties.  As a result of this
        transaction, the Corporation increased its ownership in the
        businesses operated by the joint venture from 51% to 100%.  The
        Corporation borrowed the purchase price from Thermo Electron
        through the issuance of a $35,000,000 promissory note that bears
        interest at the Commercial Paper Composite Rate as announced from
        time to time by Merrill Lynch Capital Markets plus 25 basis
        points and is due May 13, 1997.

             Thermo Electron owned approximately 80.85% of the
        Corporation's outstanding Common Stock on July 1, 1995.


        - PROPOSAL 2 -

        PROPOSED AMENDMENT TO THE CERTIFICATE OF INCORPORATION
         TO CHANGE THE NAME OF THE CORPORATION


             The Corporation's Board of Directors has proposed an
        amendment to the Corporation's Certificate of Incorporation to
        change the name of the Corporation to "Thermo TerraTech Inc." and
        has recommended that the Stockholders approve the amendment.  The
        Board of Directors has recommended this change in the
        Corporation's name to more accurately reflect the Corporation's
        transition in its principal business from industrial furnace
        equipment to environmental infrastructure services.  If the name
        change is approved by the Stockholders, (i) the Stockholders will
        not be required to surrender their stock certificates for new
        certificates reflecting the new name of the Corporation, and (ii)
        the Corporation's ticker symbol on the American Stock Exchange
        will be changed to "TTT".

        Amendment to the Certificate of Incorporation




                                       31
PAGE





             It is proposed that the name change be effected by amending
        Article First of the Corporation's Certificate of Incorporation
        to read as follows:

             "The name by which the corporation shall be known is Thermo
        TerraTech Inc."


        Recommendation

             The Board of Directors believes that the name change to
        Thermo TerraTech Inc. is in the best interests of the Corporation
        and its Stockholders and recommends that the Stockholders vote
        FOR adoption of the proposed name change.  If not otherwise
        specified, proxies will be voted FOR approval of this proposal.
        Thermo Electron, which beneficially owned approximately 80.6% of
        the outstanding Common Stock as of October 26, 1995, has
        sufficient votes to approve the proposed name change and has
        indicated its intention to vote for the proposal.

         - PROPOSAL 3  -

        PROPOSAL TO AMEND THE DIRECTORS STOCK OPTION PLAN

              The Board of Directors has approved amendments to the
        Corporation's Directors Stock Option Plan (the "Directors Plan")
        that would change the formula for granting stock options to
        purchase Common Stock of the Corporation to its outside Directors
        and would also provide for the automatic grant of stock options
        to purchase common stock of majority-owned subsidiaries of the
        Corporation created from time to time to its outside Directors,
        subject to Stockholder approval at this Meeting.

             In December 1994, as part of a review of director
        compensation, the Board of Directors adopted amendments to the
        Directors Plan, subject to Stockholder approval.  The amendments
        would first change the formula by which stock options to purchase
        Common Stock are automatically granted to outside Directors.  The
        formula, as amended, would eliminate the meeting attendance
        grants previously awarded quarterly to outside Directors under
        the Directors Plan, and also provide for the automatic grant to
        its outside Directors of stock options to purchase 1,500 shares
        of common stock of majority-owned subsidiaries of the Corporation
        spunout from time to time.  Directors would continue to receive
        an annual grant of options to purchase 1,000 shares of the Common
        Stock.

             The review of director compensation was conducted in
        conjunction with an overall review of director compensation for
        Thermo Electron and its majority-owned subsidiaries.  The purpose
        of the review was to evaluate compensation practices for the
        entire Thermo Electron family of companies, compare total cash
        compensation to comparable market data and ensure consistent and
        internally equitable compensation practices among the companies
        within the Thermo Electron family.  In connection with the
        revision of the option program for Directors, it was also agreed
        to discontinue the quarterly determination and award of stock
        options based on attendance at meetings of the Board of Directors
        and its committees, effective as of January 1, 1995. In addition,
        the Directors approved the award of a fixed number of stock
        options in majority-owned subsidiaries that may be spunout from
        time to time as part of the corporate spinout strategy of the
        Corporation and Thermo Electron.

             The spinout of business units represents an integral part of
        the Corporation's strategy, and the Corporation believes it is
        desirable and in the best interests of the Corporation and its
        Stockholders that the outside Directors of the Corporation have a
        personal equity interest in potential future spinout companies of
        the Corporation and its existing majority owned subsidiary,
        Thermo Remediation.  The Board of Directors believes that the
        award of stock options to key personnel and Directors in its
        spinout companies created from time to time serves to motivate
        individuals to contribute significantly to the Corporation's

                                       33

        future growth and success and to align the long-term interest of
        these individuals to those of all the Stockholders of the
        Corporation.  Consistent with its incentive structure for its key
        employees and executives of the Corporation, it is recommended
        that provision be made for the award of stock options to outside
        Directors in potential future spinout companies by amending the
        Directors Plan.

        Summary of the Amendments to the Directors Plan

             The full text of the Directors Plan as amended and restated
        is set forth in Appendix A, to which reference is made.  A brief
        description of the amendments to the Directors Plan follows (the
        "Amendments"), but is qualified in its entirety by reference to
        the full text of the plan.  Except as amended, the Directors Plan
        will continue in full force and effect.  A brief description of
        the material terms of the Directors Plan that are not affected by
        the Amendments are summarized under the heading "Other Terms of
        the Directors Plan."  The closing price of the Common Stock on
        October 26, 1995, was $11.375 per share.

             Initial Grant of Corporation Options

             New Directors presently are automatically awarded options to
        purchase 40,000 shares of Common Stock upon their appointment or
        election. The Amendments would reduce this amount to 16,000
        shares for new Directors appointed in 1995, and further reduce
        the size of the grant to new Directors by 8,000 shares each year
        thereafter until 1997, when the initial grant would be eliminated
        entirely.  Options may be exercised at any time from and after
        the six-month anniversary of the grant date of the option and
        prior to the expiration of the option on the fifth anniversary of
        the grant date (rather than the seventh anniversary as is
        currently the case).  Options will be subject to restrictions on
        resale and to the repurchase by the Corporation of the shares
        subject to option at the exercise price if the Director ceases to
        serve as a Director of the Corporation, Thermo Electron or any
        subsidiary of Thermo Electron, for any reason other than death.
        The restriction and repurchase rights shall lapse in equal
        installments of 8,000 shares starting with the first anniversary
        of the grant date, provided the Director has continuously served
        as a Director of the Corporation, Thermo Electron or any
        subsidiary of Thermo Electron since the grant date.  The option
        exercise price shall be determined by the average closing price
        of the Common Stock on the American Stock Exchange for the five
        trading days preceding and including the date of  the Annual
        Meeting of Stockholders.

             Annual Grant of Corporation Options

             The Amendments will discontinue, as of January 1, 1995, the
        quarterly grant of stock options to purchase Common Stock of the
        Corporation based on attendance by outside Directors at meetings
        of the Board of Directors or its committees.  The annual award of
        options to purchase 1,000 shares of Common Stock to each eligible

                                       34
PAGE





        Director as of the close of business on the date of the
        Corporation's Annual Meeting of Stockholders would be retained,
        although the terms of the award would be modified.  Options may
        be exercised at any time from and after the six-month anniversary
        of the grant date of the option and prior to the expiration of
        the option on the third anniversary of the grant date (reduced
        from the present seven year term).  Options will be subject to
        restrictions on resale and to the repurchase by the Corporation
        of the shares subject to option at the exercise price if the
        Director ceases to serve as a director of the Corporation, Thermo
        Electron or any subsidiary of Thermo Electron, for any reason
        other than death, within one year from the date of grant.  The
        option exercise price shall be determined by the average closing
        price of the Common Stock on the American Stock Exchange for the
        five trading days preceding and including the date of the Annual
        Meeting of Stockholders. 

             Grant of Subsidiary Options

             The Amendments also provide that options to purchase shares
        of the common stock of majority-owned subsidiaries of the
        Corporation will be granted automatically to eligible outside
        Directors at the close of business on the date of the first
        Annual Meeting of Stockholders following the spinout of the
        subsidiary (referred to as the "Spinout Subsidiary"), and at the
        close of business on the date of every fifth Annual Meeting of
        Stockholders thereafter during the continuation of the plan.  A
        "spinout" shall be the first to occur of either a public offering
        of the subsidiary's common stock or a private placement of such
        stock primarily to third parties in an arms-length transaction.
        At the close of business on the date of the applicable Annual
        Meeting of Stockholders, options to purchase 1,500 shares of
        common stock of the Spinout Subsidiary will be granted to each
        eligible outside Director holding office immediately following
        the meeting.  In addition, Thermo Remediation shall be deemed to
        be a Spinout Subsidiary and stock option grants will be made in
        accordance with the Directors Plan commencing with the
        Corporation's 1995 Annual Meeting of Stockholders.  A Director
        who is also a director of a Spinout Subsidiary will not be
        eligible to receive options to purchase stock of that subsidiary
        under the Directors Plan, although he or she will be eligible for
        options granted under a comparable formula plan adopted by the
        subsidiary.  The exercise price for options will be determined by
        the average of the closing prices reported by the American Stock
        Exchange (or other principal market on which such common stock is
        then traded) for the five trading days immediately preceding the
        date on which the option is granted or, if the shares are not
        then traded, at the last price paid per share by independent
        investors in an arms-length private placement of common stock
        prior to the option grant under the Directors Plan.  Options to
        purchase the common stock of a Spinout Subsidiary will vest and
        be exercisable upon the fourth anniversary of the grant date,
        unless the common stock underlying the option grant is registered
        under Section 12 of the Securities Exchange Act of 1934, as
        amended ("Section 12 Registration") prior to such date.  Section

                                       35
PAGE





        12 Registration is normally a prerequisite to the public trading
        of a security.  In the event that the effective date of Section
        12 Registration occurs prior to the fourth anniversary of the
        grant date, then the option will become immediately exercisable
        and the shares acquired upon exercise will be subject to
        restrictions on transfer and the right of the Corporation to
        repurchase such shares at the exercise price in the event the
        Director ceases to serve as a Director of the Corporation, Thermo
        Electron or any subsidiary of Thermo Electron.  In such event,
        the restrictions and repurchase rights shall lapse or be deemed
        to have lapsed at the rate of 25% per year, starting with the
        first anniversary of the grant date, provided the Director has
        continuously served as a Director of the Corporation, Thermo
        Electron or any subsidiary of Thermo Electron since the grant
        date.  The option will expire on the fifth anniversary of the
        grant date, unless the Director dies or otherwise ceases to serve
        as a Director of the Corporation, Thermo Electron or any
        subsidiary of Thermo Electron prior to that date.

        Other Terms of the Directors Plan

             A brief description of the other principal features of the
        Directors Plan that are not affected by the Amendments follows,
        but it is qualified in its entirety by reference to the full text
        set forth in Appendix A.

             Eligibility; Administration

             Directors of the Corporation who are not employees of the
        Corporation or any subsidiary or parent corporation of the
        Corporation are eligible to participate in the Directors Plan.
        The Directors Plan is administered by the Board of Directors of
        the Corporation (the "Board").  All questions of interpretation
        of the Directors Plan or of any options granted pursuant to the
        Plan are determined by the Board.

             Terms and Conditions of Options

             The exercise price for options is determined by the average
        of the closing prices reported by the American Stock Exchange (or
        other principal exchange in which the Common Stock is then
        traded) for the five trading days immediately preceding and
        including the date the option is granted, or, if the shares
        underlying the option are not so traded, at the last price paid
        per share by third parties in an arms-length transaction with the
        Corporation or the applicable subsidiary prior to the option
        grant.  The exercise price of options granted under the Directors
        Plan must be paid in full by check or by the delivery of shares
        of Common Stock (or shares of the common stock of the applicable
        subsidiary) that have a fair market value on the exercise date
        equal to the exercise price of the option.  Stock options granted
        under the plan are intended to be non-statutory stock options.
        If a Director dies or otherwise ceases to serve as a Director of
        the Corporation, Thermo Electron or any subsidiary of Thermo
        Electron, or the Corporation is liquidated, the options will

                                       36
PAGE





        terminate.  Options are evidenced by a written agreement and are
        subject to transfer restrictions that lapse as to all of the
        shares on the first anniversary of the grant date, as to annual
        grants of options to purchase Common Stock of the Corporation,
        and ratably over a four-year period as to options to purchase
        common stock of Spinout Subsidiaries of the Corporation, as
        described above under the caption "Grant of Subsidiary Options."
        Option holders will be permitted to tender shares of Common Stock
        (or shares of the common stock of the applicable subsidiary) to
        satisfy withholding tax obligations, if any.

             Change in Control Provisions

             If there is a "Change in Control" of the Corporation or its
        parent corporation, Thermo Electron, as defined in the Directors
        Plan, any stock options that are not then exercisable and fully
        vested will become fully exercisable and vested; and the
        restrictions applicable to shares purchased upon exercise of
        options will lapse and such  shares will be free of restrictions
        and fully vested.  Generally, a "Change in Control" occurs if (1)
        any person other than Thermo Electron becomes the beneficial
        owner of 50% or more of the outstanding Common Stock of the
        Corporation, or any person becomes the beneficial owner of 25% or
        more of the outstanding common stock of Thermo Electron, without
        the prior approval of the Board of Directors, or the board of
        directors of Thermo Electron, as the case may be, (2) during any
        two-year period the individuals who constituted the Board of
        Directors or the board of directors of Thermo Electron at the
        beginning of such period no longer represent a majority of such
        board, or (3) the Board of Directors or the board of directors of
        Thermo Electron determines that any other event constitutes an
        effective change in control of  the Corporation or Thermo
        Electron.

             Amendment and Termination

             The Directors Plan remains in full force and effect until
        suspended or discontinued by the Board.  The Board may at any
        time or times amend or review the Directors Plan, provided that
        no amendment that is not approved by the Stockholders of the
        Corporation shall be effective if it would cause the Directors
        Plan to fail to satisfy the requirements of Rule 16b-3 (or any
        successor rule) of the Securities Exchange Act of 1934, as
        amended.  No amendment of the Directors Plan or any agreement
        evidencing options granted under the Directors Plan may adversely
        affect the rights of any recipient of any option previously
        granted without such recipient's consent.

             Shares Subject to the Directors Plan

             The number of shares of the Common Stock that has been
        reserved for issuance under the Directors Plan is 75,000 shares.
        If the Amendments to the Directors Plan are approved by the
        Stockholders at this Meeting, an additional 25,000 shares of the
        common stock of each Spinout Subsidiary created from time to time

                                       37
PAGE





        will also be reserved for transfer upon exercise of options
        granted thereunder. Options and shares that are forfeited or
        otherwise reacquired by the Corporation will again be available
        for the grant of options under the Directors Plan.  If the
        outstanding shares of Common Stock or the outstanding shares of
        common stock of any Spinout Subsidiary are increased, decreased
        or exchanged for a different number or kind of shares or other
        securities through merger, consolidation, stock split, stock
        dividend, reverse stock split or other distribution, an
        appropriate proportionate adjustment may be made in the maximum
        number or kind of shares reserved for issuance under the
        Directors Plan.

             The proceeds received by the Corporation from exercises
        under the Directors Plan will be used for the general purposes of
        the Corporation.  Shares issued under the Directors Plan may be
        authorized but unissued shares, or shares reacquired by the
        Corporation and held in its treasury.

             Effective Date

             The Amendments will be effective as of January 1, 1995, if
        approved by the Stockholders of the Corporation at this Meeting. 

        Federal Income Tax Consequences

             The following is a summary of the principal current Federal
        income tax consequences of stock options granted under the
        Directors Plan.  It does not describe all Federal tax
        consequences under the Directors Plan, nor does it describe
        state, local or foreign tax consequences.

             The stock options granted under the Directors Plan are
        non-statutory stock options and therefore no income will be
        realized by the optionee at the time the option is granted.
        Generally, at exercise, ordinary income will be realized by the
        optionee in an amount equal to the difference between the option
        price and the fair market value of the shares on the date of
        exercise.  The Corporation receives a tax deduction for the same
        amount, and, upon disposition of the shares, appreciation or
        depreciation after the date of exercise will be treated as either
        short-term or long-term capital gain depending on how long the
        shares have been held. 

        NEW PLAN BENEFITS
         
             Only the outside Directors of the Corporation are eligible
        to participate in the Directors Plan.  The following table sets
        forth, to the extent determinable, the number of shares of the
        Common Stock of the Corporation that will be granted under the
        Directors Plan in the first year the Amendments are in effect to
        the "non-executive Director Group" if the Amendments are approved
        by the Stockholders.  Named executive officers and other employee
        groups are not set forth in the table as such persons and groups
        are not eligible to receive options under the Directors Plan.

        Recommendation

             The Board of Directors believes that the Amendments to the
        Directors Plan will enable the Corporation to ensure the
        continued services and contributions of its outside Directors and
        to attract and retain other highly qualified individuals to serve
        as outside Directors from time to time.  Accordingly, the Board
        of Directors believes that the proposal is in the best interest
        of the Corporation and its Stockholders and recommends that the
        Stockholders vote "FOR" the approval of the Amendments to the
        Directors Plan to change the formula for the grant of stock
        options to purchase Common Stock of the Corporation to outside
        Directors and to provide for the automatic grant to outside
        Directors of options to purchase common stock of the
        Corporation's majority-owned subsidiaries created from time to
        time. If not otherwise specified, Proxies will be voted FOR
        approval of this proposal.  Thermo Electron, which beneficially
        owned approximately 80.6% of the outstanding Common Stock as of
        October 26, 1995, has sufficient votes to approve the proposal
        and has indicated its intention to vote for the proposal.

        APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS
         
             The Board of Directors has appointed Arthur Andersen LLP as
        independent public accountants for fiscal 1996. Arthur Andersen
        LLP has acted as independent public accountants for the
        Corporation since its inception in 1986.  Representatives of that
        firm are expected to be present at the Meeting, will have the
        opportunity to make a statement if they desire to do so and will
        be available to respond to questions. The Board of Directors has
        established an Audit Committee, presently consisting of two
        outside Directors, the purpose of which is to review the scope
        and results of the audit.

        OTHER ACTION

             Management is not aware at this time of any other matters
        that will be presented for action at the Meeting. Should any such
        matters be presented, the Proxies grant power to the Proxy
        holders to vote shares represented by the Proxies in the
        discretion of such Proxy holders.

        STOCKHOLDER PROPOSALS

             Proposals of Stockholders intended to be presented at the
        1996 Annual Meeting of the Stockholders of the Corporation must
        be received by the Corporation for inclusion in the Proxy
        Statement and form of Proxy relating to that meeting no later
        than July 12, 1996.

        SOLICITATION STATEMENT
         
             The cost of this solicitation of Proxies will be borne by
        the Corporation. Solicitation will be made primarily by mail, but

                                       40
PAGE





        regular employees of the Corporation may solicit Proxies
        personally, by telephone or telegram. Brokers, nominees,
        custodians and fiduciaries are requested to forward solicitation
        materials to obtain voting instructions from beneficial owners of
        stock registered in their names, and the Corporation will
        reimburse such parties for their reasonable charges and expenses
        in connection therewith.
